Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) overall design technology, and in particular to an integrated detection payload cabin for UAVs. Background Technology

[0002] To enhance their reconnaissance capabilities against various targets, such as simultaneously detecting VHF / UHF communications, data links, mobile satellite communications, electronic reconnaissance, optoelectronic reconnaissance, and microwave communication reconnaissance, reconnaissance drones typically require multiple reconnaissance antennas. The placement of these antennas on the drone's fuselage is subject to certain requirements to achieve their intended functionality. For example, they should be mounted on flat areas such as the nose, sides, or back / belly of the drone, with unobstructed surroundings, to ensure sufficient spatial coverage of the antenna beam.

[0003] When a reconnaissance UAV needs to integrate a large number and variety of reconnaissance antennas, the aircraft surface may not have enough suitable area to accommodate all the antennas. Furthermore, arranging a large number of antennas on the aircraft surface can bring design challenges in terms of aerodynamics, electromagnetic compatibility, and stealth. Utility Model Content

[0004] The purpose of this invention is to provide an integrated reconnaissance payload bay for unmanned aerial vehicles (UAVs). This invention integrates the antenna within the aircraft's own payload bay, thereby improving the UAV's comprehensive mission reconnaissance capabilities.

[0005] The technical solution of this utility model is: a UAV integrated detection payload cabin, the payload cabin has a three-level stepped structure from front to back and from top to bottom, and the three-level stepped structure is surrounded by an antenna radome; wherein, the first step is equipped with a forward-looking camera, the second step is equipped with an antenna assembly, and the third step is equipped with an atmospheric sensor; the antenna radome is conformal to the shape of the UAV, and an optical window is opened on the antenna radome facing the field of view of the forward-looking camera.

[0006] In the aforementioned UAV integrated detection payload cabin, the antenna assembly includes a support frame, a support top plate on the top of the support frame, a front support frame, a side support frame A and a side support frame B respectively on the bottom surface of the support top plate along the forward and lateral directions, a front antenna is installed on the front support frame, and a side antenna A and a side antenna B are respectively installed on support frames A and B; the front end of the support top plate is connected to the first step.

[0007] In the aforementioned UAV integrated detection payload cabin, the side antenna A and side antenna B are symmetrical about the UAV and arranged in a wedge shape along the flight direction, wherein the front end of the wedge is the small end and the rear end of the wedge is the large end.

[0008] In the aforementioned UAV integrated detection payload cabin, the front support frame, side support frame A, and side support frame B are all hollow structures.

[0009] In the aforementioned UAV integrated detection payload cabin, the radome area corresponding to the boundary range of each antenna beam is the wave-transparent area of ​​the radome.

[0010] In the aforementioned UAV integrated detection payload cabin, the bottom of the radome corresponding to the boundary range of each antenna beam is provided with drainage holes.

[0011] In the aforementioned UAV integrated detection payload cabin, the first step is also equipped with a window heater for heating the optical window.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0024] Example 1. A UAV integrated detection payload cabin, configured as follows: Figures 1-8 Spatially located below the nose of the UAV, the payload bay's upper boundary is the UAV's structural floor, and its rear boundary is the UAV's structural end frame (the first end frame of the UAV body along the reverse heading). The remaining boundaries are the payload bay's radome 1. The payload bay's interior has a three-tiered structure from front to back and from top to bottom, with the radome 1 completely surrounding the three-tiered structure. The first tier houses the forward-looking camera 2, the second tier houses the antenna assembly, and the third tier houses the atmospheric sensor 3. The radome 1 is conformal to the UAV's shape, and an optical window 11 is provided on the radome 1 facing the field of view of the forward-looking camera 2.

[0025] The aforementioned antenna assembly includes a support frame 5, with a support top plate 51 on top of the support frame 5. A front support frame 52, a side support frame A 53, and a side support frame B 54 are respectively mounted on the bottom surface of the support top plate 51 along the forward and lateral directions. A front-end antenna 6 is mounted on the front support frame 52, and side antennas A 7 and B 4 are respectively mounted on support frames A and B. The front end of the support top plate 51 is connected to the first-level step. This structure enables the integrated installation of each antenna array.

[0026] The aforementioned side antennas A7 and B4 are symmetrical about the UAV and arranged in a wedge shape along the flight path, with the front end of the wedge being the smaller end and the rear end being the larger end. See also... Figure 5 The side antennas are arranged at a certain angle to the coordinate axis of the UAV body in order to obtain the required antenna radiation performance.

[0027] The aforementioned front support frame 52, side support frame A53 and side support frame B54 are all hollow structures, which are used for heat dissipation and wiring of the antenna backplate and also help to reduce weight.

[0028] The area of ​​the antenna radome 1 corresponding to the boundary range of each antenna beam is the wave-transparent area 12 of the radome.

[0029] Drainage holes 13 are provided at the bottom of the antenna radome 1 corresponding to the boundary range of each antenna beam.

[0030] The aforementioned first step is also equipped with a window heater 8 for heating the optical window 11.

[0031] An antenna processor 9 is also installed below the aforementioned support frame 5.

[0032] This invention enables the arrangement of two types of antennas and three antenna arrays within the payload bay of an unmanned aerial vehicle (UAV), while meeting the functional performance requirements of the antennas. Through a comprehensive integrated bracket design, it achieves the integrated installation of two types of antennas, three antenna arrays, and an antenna processing terminal. In addition to its reconnaissance capabilities, this payload bay integrates a forward-looking camera, an optical window, a window heater, and an atmospheric sensor. Through the radome design, it achieves the wave transmission requirements of the two types of antennas and three antenna arrays.

[0033] See Figures 2-4 Each antenna's beam array does not interfere with the others and is not obstructed by the UAV's airframe structure.

[0034] In the specific design process, in order to raise the upper boundary of the front-end antenna array, the forward-looking camera, optical window, and window heater can be omitted. The opening at the front of the payload bay radome can be eliminated accordingly, and the wave-transparent area of ​​the payload bay radome can be moved up to the lower edge of the top floor of the payload bay.
